Cell C Fibre must payback my R949.00

Cell C fibre must payback my money. I called Cell C Fibre sales call centre on 14 Sept 2020 to enquire about their CFibre and their sales agent explained the process and told me the fastest way for me to get fibre would be doing an upfront online payment and the process will be completed within 2 weeks. I paid R949.00 on the 21st Sept through the online payment link that I received and on the 25th Sept, she told me that fibre was not active within the complex while other people were connected with their ISPs. She requested proof of payments so that she can process a refund which takes 14 days to reflect. I asked her to reprocess my application since other households were active, but she insisted that there’s no coverage at my place. I eventually sent the proof payment and the docs that she requested on the 4th Oct 2020. On the 26th of October I sent an email “I haven't received my money yet; 14 days have passed. Is there a reference number that I can follow up with?” and the response from her “Good day, I highly apologies. I will escalate with the finance department.” On the 19th of Nov I called Cell C sales and found the same agent, she told me that she will put me through finance department to follow up. How do I even follow up with their finance department when there’s no direct contact person? As of 18 December 2020, Cell C have not repaid my R949.00. I am tired of calling using my airtime, I have spent more that 60 minutes on that Call centre and they put me on hold and sometimes if I’m lucky the same agent who assisted me who does not even know what the reason of the delay on her end is.
